I had it in to the dealer for a "free service clinic." Basically they look over my car, note needed repairs, and wash it, while I raid their deli platter and watch the NCAA tournament in the waiting room. Of course, this is an upselling opportunity for them. So they recommended 1) lower ball joints, 2) front A frame bushing, 3) front sway bar bushings, and 4) shock covers. But they basically admitted there's no pressing reason to deal with the last three.
